This paper is an expanded and more detailed version of the work [1] in which the Operator Quantum Error Correction formalism was introduced. This is a new scheme for the error correction of quantum operations that incorporates the known techniques — i.e. the standard error correction model, the method of decoherence-free subspaces, and the noiseless subsystem method — as special cases, and reli...

The Device Remote Monitoring System (DRMS) based on network is designed and implemented in order to integrate the decision making level, the monitoring level and the field level together effectively, whose architecture is the hierarchical control architecture including three layers: low-layer, mid-layer and upper-layer. The low-layer is the multimedia fieldbus system (MFS), the mid-layer is the...

We study the problem of satisfying maximum number distance geometry constraints with minimum experimental error. This models determination shape proteins from atomic data which are obtained nuclear magnetic resonance experiments and exhibit systematic errors. Experimental errors represented by interval on Euclidean distances. Systematic occur a misassignment distances to wrong pairs: we represe...

Working within the framework of the propositional system formalism, we use a previous study [1 ] of the description of two independent physical systems as one big physical system to derive a characterization of a (non-interacting) physical subsystem. We discuss the classical case and the quantum case.

The subject under study is an open subsystem of a larger linear and conservative system and the way in which it is coupled to the rest of system. Examples are a model of crystalline solid as a lattice of coupled oscillators with a finite piece constituting the subsystem, and an open system such as the Helmholtz resonator as a subsystem of a larger conservative oscillatory system. Taking the vie...

Many successful modelling studies are conducted without venturing beyond the techniques described in Part II. In other words, the system characteristics considered in these studies are restricted to those that can be represented directly using the parameters of separable queueing networks. There are, of course, situations in which the analyst will wish to represent a specific subsystem in great...
